BACKGROUND OF THE INVENTION

This invention relates to accessories for electronic devices and morespecifically to cases for portable electronic devices and electronictablets.

With each new generation, portable electronic devices provide greaterfunctionality and have more capabilities. These portable electronicdevices allow people to play and record music, send and receive e-mail,send text messages, browse Web pages, make phone calls, play and recordvideo, take and view pictures, edit documents, and much more. Thesedevices continue to revolutionize the way people interact, learn,connect with other people, conduct business, and find things. They helppeople manage their daily lives and can be a source of entertainment.These devices can be used to store valuable information includingpersonal information (e.g., phone numbers, financial information,private photos or videos, and favorite music tracks).

Typically these devices are intended to be carried or moved about. Assuch, these devices are more vulnerable to damage as compared tononportable devices. These devices are more likely to be accidentallydropped, hit, or scratched. Some types of damage may be cosmetic (e.g.,scratch). However, other types of damage may ruin or limit thefunctionality of the device. Often these devices contain sensitive andfragile components (e.g., screen, camera lens, flash, processors,accelerometers, and sensors). Accidentally dropping the device couldrender various features unusable.

Protective cases are used to protect these devices from possible damage.It is desirable that these cases allow users to use the functionality oftheir devices, while devices remain in their cases. Cases can also beused to enhance the functionality and capabilities of the device.

Therefore, there is a need for cases for portable electronic devicesthat will protect the devices, while at the same time enhance thefunctionality and usability of the devices.

Any trademarks listed in this patent application are theproperty of their respective owners

Portable electronic device are valuable because their functionality, theinformation they contain, and time and expense to replace. A case istypically much easier and less expensive to replace than the devicewhich it houses and protects.

A case protects the portable electronic device from scratches, dings,dents, and other damage. The case also provides shock absorption. Thecase will absorb impacts, preventing shock to the components of thedevice which are often delicate. The case can also improve the grip tothe device and case combination. The case may include a texture pattern,be made from a tacky material, or have a tacky coating, or include awrist or neck strap. The case may also be waterproof or water resistantto protect the device from rain, snow, and surf.

A case may include a battery to lengthen a battery life of the device. Abattery case is described in U.S. Pat. No. 7,612,997, issued Nov. 3,2009, which is incorporated by reference. A case may include a stand(e.g., built-in stand). With such a stand, a user can stand the deviceon a table and watch the screen hands-free. Some examples of some casedesigns are in U.S. patent application 61/365,302, which is incorporatedby reference along with all other references cited in this application.

This patent application incorporates by reference U.S. Pat. Nos.7,612,997, issued Nov. 3, 2009; D587,896, issued Mar. 10, 2009;D582,149, issued Dec. 9, 2008; D581,151; D579,213, issued Oct. 28, 2008;and D575,056, issued Aug. 19, 2008. These patent applications areincorporated by reference.

A case is typically an important accessory for the device that itprotects. For, a person might accidentally drop a portable electronicdevice in the case on the floor when running to catch a flight for abusiness trip at the airport. The case may cushion the drop, thuspreventing major damage to the portable electronic device. The portableelectronic device will remain intact and unbroken, saved by the case.The person can pick up the portable electronic device, continue on theflight, and use the portable electronic device on the business trip.

If the portable electronic device had not been protected by a case, theportable electronic device might have become broken. The screen maybecome cracked or there might have been other damage rendering thedevice inoperable. The person typically would not have been able toreplace the portable electronic device soon enough, especially if therewas important information saved on the portable electronic device (e.g.,sales presentation slides) that are needed for the business trip.

FIGS. 1A-1E show different views of a case for an electronic tabletdevice. As discussed above, this case may also be used for other typesof electronic devices including, for example, electronic book readers,electronic books, personal digital assistants (PDAs), and smartphones.

FIG. 1A shows a front view of the case. The case has an elastic bandclosure 103. When the case is in a closed position (as shown in FIGS.1A-1E), the elastic band secures a front flap 106 of the case againstthe screen of the electronic device; this protects the screen fromdamage.

FIG. 1B shows a side 109 view of the case, showing a spine panel 110 ofthe case. FIG. 1C shows a side 112 view of the case. FIG. 1D shows aside 115 view of the case. FIGS. 1C and 1D show a sleeve 117 which holdsthe electronic device. Sides 112 and 115 of the sleeve have openingsthat allow access to ports and like features of the electronic device.

FIG. 1E shows a back view of the case. The case has a back flap 119.Elastic band 103 is attached to the back flap at locations 127 and 125of the back flap. So, the elastic back is stretched to hold the frontflap to the back flap with tension, thus securing the electronic device(in the sleeve) between the flaps.

The case can be folded to act as a stand for the electronic device. Tofacilitate the case being folded or converted into a stand, the backflap of the case has a crease hinge 129. Further details follow below.The front flap does not have a hinge, crease or otherwise, runningthrough it.

In a specific implementation, the flaps of the case have rounded corners131, 133, 135, and 137. Rounded corners provide a smoother edgingwithout hard angles, which makes sliding into a bag easier and lesslikely to catch. Rounding also helps prevent bending or dog-earing ofthe corners.

In a specific implementation, a length of the case is about 250millimeters (about 9.8 inches), and a width of the case is about 200millimeters (about 7.9 inches). The case (or spine) is about 30millimeters (about 1.2 inches) thick. These dimensions of the case canvary to accommodate the electronic device being housed. There areopenings in sides of the case that allow access to ports and buttons ofthe electronic tablet without needing to remove the electronic tabletfrom the case. The case has a back surface with a groove, break, orcrease that allows bending of this back surface to make a stand for theelectronic tablet.

FIGS. 1F-1H shows front, side, and back views of a specificimplementation of a case.

The case has a built-in stand feature that allows for multiple viewingangles. FIGS. 2A-2H show the case being used as a stand for theelectronic device, where the stand is in a landscape orientation. FIG.2A shows a front perspective view the open case after the case has beenconverted, by folding, into a stand. FIG. 2B shows a back perspectiveview. FIG. 2C shows how the sleeve and front flap of the case can beadjusted to be placed into one of three viewing angles. FIG. 2D shows afirst viewing angle, FIG. 2E shows a second viewing angle, and FIG. 2Fshows a third viewing angle. FIG. 2G shows a close-up view of an edge204 of the front flap placed into a groove 206 that holds the case atthe first viewing angle. FIG. 2H shows the case folded in a workingangle view position.

As shown in FIGS. 2A-2G, in a specific implementation, there are threegrooves 206, 208, and 210 in a back (or inside surface) of the frontpanel 106. These grooves are used to form a built-in stand for thedevice. There are multiple grooves (such as three) to permit multipledifferent viewing angles. Three grooves allow for positioning thedisplay of the electronic device into three viewing angles, viewingangle 1 (FIG. 2D), viewing angle 2 (FIG. 2E), and viewing angle 3 (FIG.2F). These viewing angles are different from each other. There is noneed to flip or turn the case upside down to access any of the differentviewing angles. The viewing angle may be adjusted by sliding edge 204 ofthe sleeve forward or back along the back of the front panel until itfits into one of the grooves. The electronic device need not be removedfrom the case to use the stand feature of the case.

In other implementations, there may be fewer grooves, such as one ortwo, which would allow for fewer than three viewing angles. For example,two grooves allow for two viewing angles, and one groove allows for oneviewing angle. There may be more than three grooves (e.g., four, five,six, or seven) to allow for more than three viewing angles. For example,four grooves allow for four viewing angles, and five groves allow forfive viewing angles. Additionally, the case can allow for a viewingangle when not using any of the grooves. For example, the case has aworking angle view (FIG. 2H) which is discussed below.

In an implementation, the case is made from a neoprene material.Neoprene provides cushioning and shock absorption for the device whichthe case protects. However, in other implementations, other materialscan be used including silicone, rubber, fabric, and many others. Otherexamples of case material include vinyl, polyvinyl chloride (PVC),plastic, thermoplastic, cloth, leather, artificial leather, syntheticleather, synthetic leather made of plastic (sometimes referred to aspleather), poromeric imitation leather, koskin, leatherette, metal(e.g., stainless steel, aluminum, or titanium), and carbon fiber.

In FIG. 2A, a representative electronic tablet device 215 is shown insleeve 117 of the case. The screen of this electronic tablet is viewablethrough a front opening 219 formed in a bezel 222 of the sleeve. Thebezel surrounds the front opening on four sides, holding the electronictablet in the sleeve so that the electronic tablet can not easily comeloose or detached from the case.

Through the front opening, a user can view the entire screen. In animplementation, the front opening has about a 4:3 aspect ratio. For246-millimeter (9.7-inch) diagonal screen size, the front opening has alength of at least about 198 millimeters (7.8 inches) and a width of atleast about 147 millimeters (5.8 inches). In other implementations, theaspect ratio may vary slightly or be different, such as 16:9 or 16:10.

Typically, the size of the front opening is larger than the screen sizeof the electronic device to allow the user access to any buttons,controls, or ports in the front of the device. Also by making the frontopening larger than the screen, if the electronic tablet were to shiftin position in the sleeve slightly, the entire screen would remainvisible and not be partially blocked by the bezel. The sides of thesleeve can have die cut openings or holes 225 positioned to allow accessto controls and ports of the electronic tablet. The tablet device doesnot need to be removed from the case to view the screen or access thedevice's controls or ports.

Referring to FIGS. 2D-2F, the front flat of the case is rigid and formsa flat base surface 228 of the stand. This relatively large flat basesurface gives stability when the case is used as a stand. A length ofthe flat base surface is at least about 200 millimeters (width of thecase), while a width is about 250 millimeters (length of the case).Regardless of which viewing angle is being used (FIG. 2D or 2E or 2F),the flat base surface of the stand will be at least a footprint size ofthe front flap.

The flat base surface feature of the case makes the stand unlikely torock or tip over when it is used. For a tablet stand without arelatively large flat base surface, it is easier for someone toaccidentally knock the tablet and have it flip over and drop off, forexample, a table onto a hard floor. By contrast, when the case in FIG.2A is accidentally knocked, the tablet would fall back and fall onto thefront flap, but the relatively large flat base surface would prevent thetablet from dropping on the floor. With the case of the invention,damage to the tablet is avoided.

In an implementation, the spine has a length of about 30 millimeters andthe flat base surface a length of about 200 millimeters. A length of theflat base surface (in a direction perpendicular to the bottom edge ofthe sleeve) is at least 2 times greater than the spine length. This willprovide greater stability for the stand than having a footprint lengthof only the spine. In various implementations, the length of the flatbase surface is at least 3 times greater than the spine, at least 4times greater than the spine, at least 5 times greater than the spine,or at least 6 times greater than the spine length. Further, forstability, wherever the sleeve is placed on the flat base surface tomake a stand, a portion of the flat base surface will be behind thesleeve and a portion will be in front of the sleeve.

In operation, a case in the closed position, such as shown in FIGS.1A-1E, is opened and unfolded into the stand position shown in FIGS.2A-2G. Elastic band 103 is stretched and flipped from the front flap tothe back flap as shown in FIG. 2B. Referring to FIGS. 2A and 2B, thestand has three hinges that facilitate folding the case into a stand.Hinge 129 is on the back flap, while hinges 238 and 234 are positionedon either side of spine 110.

FIG. 2H shows the case in a working angle position. The working angle isless sloped than the other three viewing angles described in FIGS.2D-2F. The working angle is more ergonomic for when the user wants totype on an on-screen keyboard, such when a student takes notes in aclassroom. For the working angle, the edge of the back of the case isnot placed in any of the viewing angle grooves. The back of the case isfolded to provide the working angle slope, and the elastic band is usedto hold the case in the working angle position.

For the working angle position, edge 204 of the sleeve is not placedinto any of the grooves. Rather, hinge 129 is folded until sides 241 and243 of the back flap 119 (on either side of hinge 129) come into contactwith each other. Spine 110 is rotated (via hinges 238 and 234) intoposition to lift and tilt the sleeve and electronic tablet into theworking angle. The working angle can vary depending on the rotation ofthe hinges 238 and 234.

In a specific implementation, hinges 238 and 234 are rotated so that thespine is approximately perpendicular with respect to flat base surface228. However, the spine can be rotated so that it is in an angle (e.g.,30, 45, 60, or 0 to 90 degrees) with respect to the flat base surface togive the desired working angle tilt. As shown in FIG. 2H, elastic band103 can be stretched over the folded sides 241 and 243 and flat basesurface 228 to hold the stand in the working angle position usingtension.

FIG. 2H also shows a latch 246. The latch spans across a slot 247 of thesleeve and holds the electronic device in the sleeve. The latch can beremovably secured using hook-and-loop fastener (e.g., Velcro) with anattachment point on an underside of the bezel. Other types of fastenersmay be used. With the latch detached, the electronic device can beinserted into or removed through the slot of the sleeve. Thus, the latchkeeps the electronic device removably secured within the sleeve.

FIG. 2I shows another side view the case being used as a stand for theelectronic device. As discussed above, the case has crease hinge 129 tofacilitate folding the case into a stand. Crease hinge 129 on the backflap is at a position below the top edge of the back of the sleeverather than at the top edge of the sleeve. This positioning allows theback flap to be folded into the working angle shown in FIG. 2H.

At the option of the user, the contents of screen of the electronicdevice may viewed in the landscape orientation (e.g. for a movie) orportrait orientation (e.g., for a Web page). The orientation may bechanged by simply flipping the screen ninety degrees (which is sensed byan internal accelerometer of the electronic device). The case of theinvention supports this feature of the electronic device.

FIGS. 3A-3C show the case being used as a stand in the portraitorientation. FIG. 3A shows a front perspective view of the casepartially opened in the portrait orientation. FIG. 3B shows a frontperspective view of the case in the portrait orientation where the frontflap has been flipped open to expose the screen of the electronicdevice. FIG. 3C shows a top view of the case in the portraitorientation.

FIG. 3B shows the grooves on an inside surface of the front flap formultiple viewing angles when the case is in the landscape orientation.In the portrait orientation, the grooves may not be used. Rather, whenthe case is folded into a stand having the portrait orientation, theedges of the case provide the stability for the stand.

Referring to FIG. 3C, hinges 129, 234, and 238 allow the front and backflaps, spine panel, and sleeve edges to be independently positioned sothat there is sufficient stability to hold the electronic device in theportrait position. When the touch screen display of the device is used,this stand is unlikely to tip over because the stand can resist thetouch forces being applied to the touch screen.

Also, the placement of hinge 129 allows turning the screen to allow agreater unblocked viewing angle. More people can view the screen at thesame time. The screen will not be blocked or partially blocked by thefront flap, which may prevent a person viewing from the left of thescreen (when the flap is on the left-hand side as in FIGS. 3A-3C). Theoutline of the stand in FIG. 3C is an open polygon. However, byadjusting the pivoting of the hinges, an edge of the sleeve can touchthe front flap to form a closed polygon.

FIG. 4A shows an inside of the case. There is a bezel to hold theelectronic tablet. An interior surface inside the case, against which aback of the electronic tablet is placed, is suede backed with a debossedprint pattern. In an implementation, the pattern is a topographicpattern. Some examples of topographic patterns are in U.S. Pat. Nos.D579,213, issued Oct. 28, 2008; D581,151, issued Nov. 25, 2008; andD587,896, issued Mar. 10, 2009. Various materials can be used for theinterior surface including microfiber, velvet, silicone, rubber, fabric,and carbon fiber. The material may be tacky to grip the back of theelectronic tablet, and also provide cushioning to protect the electronictablet. The backing can grip the back of the electronic tablet withoutscratching or otherwise damaging the back of the electronic tablet.

In FIG. 4A, a debossed textured pattern is formed by printing onto thesuede material. The pattern forms grooves, indentations, or recessesinto the suede material. Other textured patterns may be used such as anembossed pattern having raised features, rising from or on the surfaceof the material. Some processes to form the texture pattern may includeetching, silk-screening, stamps, dies, rollers, thermal printing,deposition, coating, and many others. The pattern may includetopographic lines as shown in FIG. 4A, vertical lines, horizontal lines,diagonal lines, dots, shapes (e.g., circles, rectangles, boxes), orcombinations of these.

The pattern can help to removably grip the back of the electronic deviceand prevent the electronic device from sliding or shifting within thesleeve. The pattern can increase the friction between the back of theelectronic device and the sleeve. With the bezel, textured backing, andlatch, the case will hold electronic device securely. There will not bea need to apply an adhesive, adhesive strip, double-side tape, or thelike to the back of the electronic device, which may damage or mar theback of the device.

Instead of printing pattern to provide texture in the sleeve, tacky ortexture materials may be formed, molded, or attached on the sleevebacking. For example, a protective spine (see below) or slider rails maybe positioned in the sleeve backing. The protective spine or sliderrails may be made from a material such as silicone, rubber,thermoplastic elastomer, carbon fiber, or the like.

The table below provides a specific example of a flow for making thecase. In conjunction with the table, FIGS. 5-9 show the case at specificpoints in the flow. FIG. 5 shows a front view of an outer cover 610which forms the front and back flaps and spine panel of the case. FIG. 6shows a front view of sleeve 117. FIG. 7 shows a front view of elasticband 103. FIG. 8 shows a top view of the assembled pieces of the case.FIG. 9 shows a cross section of the assembled pieces of the case.

It should be understood that the invention is not limited to thespecific flows and steps presented. A flow of the invention may haveadditional steps (not necessarily described in this application),different steps which replace some of the steps presented, fewer stepsor a subset of the steps presented, or steps in a different order thanpresented, or any combination of these. Further, the steps in otherimplementations of the invention may not be exactly the same as thesteps presented and may be modified or altered as appropriate for aparticular application or based on the data or situation.

TABLE Step 1 Form outer cover 610. See FIG. 5. Step 2 Make hinges 238,234, and 129 in outer cover. This divides the outer cover into the frontflap, back flap, and spine panel. See FIG. 5. Step 3 Make grooves 206,208, and 210 in outer cover. See FIG. 5. Step 4 Form sleeve 117. SeeFIG. 6. Step 5 Create bezel of sleeve, and slot and latch. See FIG. 6.Step 6 Position sleeve on back flap. Position ends of elastic band (FIG.7) between sleeve and back flap. FIG. 8 shows a top view, while FIG. 9shows a cross section. Step 7 Attach sleeve, elastic band, and outercover to finish the case.

In step 1, to form outer cover 610, there is a rectangular sheet ofmaterial cut to the desired dimensions to form the case. For example, alength of the material may be at least about 430 millimeters (about 16.9inches) and a width of at least about 250 millimeters (about 9.8inches). The length of material may be about at least twice or two timesthe width of the front or back flap. A single sheet layer may be used.For example, the single layer may be a thermoplastic or other plastic orpolymer.

Alternatively, multiple or composite sheets or layers may be used.Leather, synthetic leather, or vinyl can be used to sandwich a morerigid material or stiffening layer, such as flexible plastic orcardboard. An additional layer may be a foam or other padding material.A foam or padding layer can help to provide cushioning for theelectronic device. There can be layers other than those described above.

For example, there can be first and second flexible layers and fourrigid or stiffening (or padding such as foam, or both) layers. The rigidlayers are to be sandwiched between the first and second flexiblelayers. The rigid layers will form the front and back flaps and spinepanel of the case. The first flexible layer will form the outsidesurface of the case. The second flexible layer will form the insidesurface of the case. The first and second flexible layers have about thedesired dimensions of the outer cover when the outer cover is laid flatand open. The composite layers can be combined or attached together bystitching, adhesives, bonding, glue, fusing, or the like.

In step 2, hinges are formed in the outer cover. In a specificimplementation, to make a hinge, the first and second flexible layersare sealed or otherwise fused together to form a seam. On one side ofthe seam there is one rigid layer and on another side of the seam thereis another rigid layer. The seam forms the crease hinge (or fabrichinge) and the rigid layers can swing about the flexible material of thecrease hinge.

More specifically in this specific implementation, in a substep 2 a, arigid layer representing the front flap is placed on the first flexiblelayer. In a substep 2 b, a rigid layer representing the spine panel isplaced on the first flexible layer. The spine panel rigid layer isplaced next to or adjacent to the front flap rigid layer. In a substep 2c, the second flexible layer is placed over the rigid layers and thefirst flexible layer. In a substep 2 d, the first and second flexiblelayers are sealed together to form a seam. The front flap rigid layer ison one side of the seam. The spine panel rigid layer is on an oppositeside of the seam. The seam forms the crease hinge, i.e., crease hinge238 and the front flap and spine panel can swing about the crease hinge.Other hinges 234 and 129 can be made similarly to hinge 238.

In a specific implementation, the hinges show as visible crease lines inthe outer cover. The material (e.g., plastic, fabric, or leather) at thecrease line can be flexed in a hinge-like fashion—allowing flaps orpanels connected by a hinge to swing or rotate with respect to eachother.

Other hinges and techniques of forming hinges may be used in a case ofthe invention. Some hinges include fabric hinges, living hinges, pianohinges, continuous hinges, butt hinges, butterfly hinges, flush hinges,barrel hinges, concealed hinges, and spring hinges. The hinge can bemade from materials including fabric, leather or other natural skinmaterials, synthetic leather, microfiber or polyester, metal (e.g.,brass), plastic (e.g., polypropylene, polyethylene, or thermoplastic),rubber, silicone, carbon fiber, and others.

Other hinge techniques may not result in visible creases in thematerial. These hinges may be referred to as invisible or hidden hinges,but these hinges allowing flaps or panels connected by a hinge to swingor rotate with respect to each other.

In step 3, grooves are formed in the outer cover. These grooves are usedto hold the edge of the sleeve when the case is used as a stand in thelandscape orientation. Each groove is an indentation, which the sleeveedge can rest in, to prevent the sleeve from sliding backwards orforwards on flat base surface 228. The groove projects into or below theinside surface of the base surface. A depth of the groove is less than athickness of the front flap. A groove may also be also referred to as achannel, recess, cavity, depression, indentation, notch, passage,furrow, slot, or flute. Typically, each groove is formed as a line (206,208, and 210) that extends across the entire base surface as shown inFIG. 5.

To make the grooves, the material in the base surface of the front flapis depressed (or compressed together) to result in a plasticdeformation. This may be done by a pressing a hard material (e.g.,metal) at the position of a groove.

In another implementation, making the grooves may use a techniquesimilar to making the hinges. In a specific implementation, to make thegrooves the outside and inside flexible layers are not sealed togetherat the grooves. This is so that at the grooves the front flap remainsrigid and resists bending about the grooves. Rather, the rigid frontflap layer will form the base of the grooves. There are additional layerstrips on each side of the groove which define the walls or sides of agroove.

More specifically in this specific implementation, in a substep 3 a, afirst additional layer strip is placed on the rigid front flap layer. Ina substep 3 b, a second additional layer strip is placed on the rigidfront flap layer. The second additional layer strip is placed next toand is spaced apart from the first rigid layer strip. The spacingbetween the additional layer strips indicates a width of the groove tobe made. In a substep 3 c, the inner flexible layer is placed over therigid front flap layer and the first and second additional layer strips.In a substep 3 d, the inner flexible layer is sealed together with therigid front flap layer to form a groove. The first and second additionallayer strips are on either side of the groove and the thickness of theadditional layer strips form the walls of the groove. The rigid frontflap layer forms the base of the groove. The other grooves may be formedusing a similar technique.

The grooves act as a stop mechanism or edge stop to hold the sleeve andprevent the sleeve (and thus electronic device) from slipping or slidingout of place. Specifically, grooves hold the sleeve in the variousviewing angles shown in FIGS. 2D-2F. With the grooves, the user does nothave to physically hold or touch the case to keep the device in aselected viewing angle.

Other stop mechanisms may be used to retain the edge of the sleeve toprevent the sleeve from sliding and keep the sleeve stationary at theselected viewing angle. These other mechanisms may be used instead of orin combination with grooves. For example, in another specificimplementation, there are one or more rails or other projections thatemerge or project above flat base surface 228. The projections may beprotrusions, anchors, levees, studs, posts, and the like.

In an implementation, the projection is an extra layer of materialattached to the base surface. For example, a strip of material isattached (e.g., glued or fused) onto the flat base surface to form therails. There may be three rails to prevent the sleeve from slidingforward. In this implementation, the projection and front flap are twoseparate pieces of material. Alternatively, the rails or projections maybe molded as part of the flat base surface.

Also, the strips of material may attached to an inner layer of therectangular sheet of FIG. 5. Then, the outer layer will also have aprotrusion caused by the inner strips of material.

In this specific implementation, the projection extends in a directionacross flat base surface, similarly to the groove lines as shown as FIG.5. The projection or rail may extend as a single line from one edge ofthe base surface the opposite edge. A length of the projection will beabout the same as a length of the case.

However, in other implementations, the length of the projection is lessthan the length of the case. Specifically, the projection may be asingle rail approximately centered between the two edges (where thereare gaps between the edges and where the rail begins).

As a further example, the projection or rail can be a series ofprojections (e.g., analogous to a broken line with two or moresegments). Also the projection can be one or more studs, posts, orbuttons extending from the inside surface of the front flap to stop thesleeve from sliding. The projection may be referred to as a ridge orbump. The can be one or more of these posts used for each viewingposition.

In a specific implementation, a thickness of a rail is less than orequal to a thickness of the bezel. Further, the rail is positioned onthe front flap such that there is a first gap between a top edge of theflap and an end of the rail, and a second gap between a bottom edge ofthe flap and an opposite end of the rail. The lengths of the gaps aregreater than or equal to a width of the bezel. This allows the frontflap to be closed over the bezel where the thickness and location of therail does not interfere with the inside surface of the front flappressing against the bezel.

In another implementation, one or more rows of fasteners (e.g., buttons)are attached lengthwise along the inside surface of the front flap. Inthis specific implementation, the method includes providing a striphaving a series of corresponding fasteners to act as the stop. The usercan fasten the strip to the inside surface of the front flap and thesleeve will butt against the fastened strip to act as a stop at thedesired viewing angle.

There can be an extra layer of material added to the base surface to actas the stop mechanism. There can be one or more flaps of material addedto the base surface to make inner sleeves (which can also be used tohold papers) for the case.

In step 4, to form the sleeve 117, a rectangular sheet of material cutto the desired dimensions to form the backing (FIG. 4A) of the sleeve.For example, a length of the backing may be at least about 250millimeters (about 9.8 inches) and a width of at least about 190millimeters (about 7.5 inches). The backing can be a single sheet layeror multiple layers, such as described for the outer cover described instep 1 above.

In an implementation having multiple layers, a suede surface of thebacking is printed with a debossed pattern to provide a textured surfacethat will grip the electronic device. The suede surface is combined witha stiffening layer, and a sleeve back layer. The stiffening layer issandwiched between the sleeve back layer and the suede layer, which willbe against the back of the electronic device.

Sides of the sleeve are made from material. This side material may bedie cut with openings appropriate for the electronic device. Othermanufacturing techniques to make a hole include cutting, punching, ordrilling. Case openings are further described in U.S. patent applicationSer. No. 12/847,887 filed Jul. 30, 2010 which is incorporated byreference

As previously discussed, the sleeve has bezel 222. In step 5, the sleevebacking, sleeve sides, and bezel are attached together. For example,they may be attached by stitching, an adhesive, bonding, or other.

One of the sides of the sleeve will remain open to allow for slot 247.The slot also has a latch 246. This latch may be a piece of materialthat will go across the slot, which will block the electronic devicefrom dropping out of the slot. Latch 246 can have a width of material asshown in FIG. 2H, or the width of the latch may run the entire length ofthe slot.

In step 6, the sleeve is positioned on the back flap as shown in FIG. 8.FIG. 9 shows a cross-sectional view. Hinge 129 is shown using a brokenline to indicate that it is behind the sleeve. In an implementation,ends of elastic band 103 (FIG. 7) are positioned between the sleeve andthe back flap. The elastic band wraps around a top edge of the backpanel, extends across an outside surface of the back panel, and wrapsaround a bottom edge of the back panel. The elastic band is oriented sothat it runs parallel with the case hinges (FIGS. 8-9).

In step 7, the sleeve, elastic band, and outer cover are attachedtogether to finish the case. In an implementation, the sleeve, elasticband, and outer cover are stitched together along the edges of thepieces, to the right of hinge of 129 (as represented in FIG. 8).Optionally, an adhesive or glue 925 (FIG. 9) may also be used betweenthe back of the sleeve and outer cover. Alternatively, adhesive 925,without stitching, may be used to attach the pieces of the casetogether.

Between hinge 129 and 234, this portion of the outer cover is notattached to the sleeve. Not fixing the sleeve to the movable back flapportion allows the movable back flap to swing or move independently ofthe sleeve and allows the sleeve to be positioned at the desired viewingangle, working angle, or both. Hinge 129 is not attached to the sleeveso that it can swing and rotate freely.

In an implementation, the elastic band is provided as a strip, i.e.,having an end and an opposite end. In another specific implementation,the elastic band is provided as a loop, i.e., a continuous strip orcircle of band material.

The band may be referred to as a belt, strap, strip, or cord. Typically,the band is thin so that it remains unobtrusive. A cross section of theband is rectangular and when viewed in cross section the band has alength that is substantially greater than a width. Alternatively, theband can be thick. The band can have a square cross section or acircular cross section (e.g., bungee cord).

In a specific implementation, the band includes an elastic type materialthat is capable of being easily stretched and recovering size and shapeafter deformation. The band may include materials such as rubber,silicone, gum, latex, cloth, fabric, nylon, leather, or combinations ofthese. Alternatively, the band may be designed so that it is not to bestretched like a rubber band. In this specific implementation, the bandmay be webbing, i.e., a strong narrow closely woven fabric. Buckles,hook-and-loop fasteners, buttons, and the like may be provided so thatthe band webbing can removably secure the front flap to the back flap.

FIG. 8 shows a top view of an open case. In an implementation, grooves206, 208, and 210 are approximately equally spaced from each other. Theviewing angles the case provides for include about 45, 60, and 75degrees. The working viewing angle is about 8 degrees. In anotherspecific implementation, the viewing angles are about 34, 50, and 60degrees.

However, in other implementations, the grooves are not equally spacedfrom each other. Also the viewing angles will be different from thoselisted above. The selected viewing angle will be between about 0 degreesand about 90 degrees, such as 30, 31, 32, 33, 34, 35, 36, 37, 38, 39,40, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61,62, 63, 64, 65, 70, 75, 80, or 85 degrees (or any combination of these).The working viewing angle can range from about 5 degrees to about 15degrees, such as 6, 7, 8, 9, 10, 11, 12, 13, or 14 degrees.

Referring to FIG. 9, the sleeve has slot or side opening 247 which isindicated by the dashed lines. A removable latch (shown in FIG. 2H)spans across the slot to removably secure the electronic device withinthe sleeve. The slot is on a side of the sleeve that is nearest to thespine panel. A length of the slot is parallel with a length of the case,elastic band, or both.

When the case is closed as shown in FIG. 1A the slot will be covered bythe spine panel of the case. This location of the slot with respect tothe sleeve sides allows for a relatively small amount of latch materialto be used, but still allows the slot to be covered when the case isclosed, thus protecting the electronic device. For example, when thelatch is closed the side of the electronic device is still visiblethrough the slot. When the case is closed the slot will be covered bythe spine panel and the side of the electronic device will not bevisible.

Using a small amount of latch material lowers the overall cost of thecase because less material is used as compared to having a latch thatcompletely covers the slot. Using less material also makes the case lessheavy which makes the case easier to carry.

It should be appreciated that the slot can be located on any side of thesleeve. In another specific implementation, the slot is located on aside of the sleeve opposite from the side shown in FIG. 9. That is, theslot is on a side of the sleeve nearest the elastic band, furthest fromthe spine panel, or both. In another specific implementation, the slotis located on a side of the sleeve transverse to the side shown in FIG.9. That is, a length of the slot is transverse or perpendicular to thelength of the case, the elastic band, or both. The length of the slot isparallel with a width of the case.

Further, the latch for the slot shown in FIG. 2H is merely one type ofretention mechanism that may be used to removably secure the electronicdevice within the sleeve. Other retention mechanisms may be used insteadof or in addition to the latch and hook-and-loop fastener shown in FIG.2H. For example, in another specific implementation, one or more buttonsare used instead of the Velcro so that the latch is removably snappedacross the slot. In another specific implementation, the retentionmechanism includes a long flap that extends out from the bezel, wrapsaround the side of the electronic device, and tucks under the electronicdevice to removably secure the device within the sleeve. In anotherspecific implementation, a zipper is stitched or otherwise attached tothe slot to open and close the slot.

The case has a band to hold front flap of the case against the sleevewhen in the closed position. FIGS. 1A and 8-9 show the positioning ofband 103. Referring to FIG. 9, the band is positioned between hinge 129and a right side edge 940 of the outer cover. Generally, the band ispositioned so that it is closer to the right side edge than hinge 129.This allows for the user to more easily pull the band over the frontflap.

In an implementation, when the case is closed as in FIG. 1A, the bandrests on the front flap at a position further away from the spine thanan edge 955 opposite the spine. A distance from edge 955 to the bandwill be greater than a width of the band, and greater than a distancefrom the band to the spine.

In an implementation, the band has a width of about 20 millimeters unitsand the distance from edge 955 to the band is about 25 millimeters,where the front flap is about 200 millimeters. So the band is about 10percent of the front flap, and edge 955 to the band is about 125 percentof the band width. The percentages can vary such as 6 to 15 percent forthe band width, and 100 to about 150 percent for edge 955 to the band.

In implementation, a distance from edge 955 to the band is in a rangefrom about 5 to 10 millimeters, about 15 to 30 millimeters, or up toabout 80 millimeters from the edge. These distances allows for ease inslipping on and off the band, but is also a sufficient distance so theband does not accidently slip off.

Since the band is attached to the case, the band is unlikely to becomelost or misplaced. The positioning of the band allows the band to beeasily pulled over the right side edge of the back flap to secure andunsecure the front flap to the back flap. As shown in FIG. 2H, the bandholds the back flap together for the working angle.

In an implementation, as shown in FIG. 9, ends of the band are attachedbetween the sleeve and the outer cover. In other implementations, theends of the band may be attached at different points of the outer cover.For example, the band may be attached at points on the back flap 119 ofFIG. 1B (such as part 241 of FIG. 2H). The band may be attached atpoints on an inside of back flap 119.

In an implementation, the band can be a continuous piece or loop ofmaterial. There can be multiple bands, e.g., two or more elastic bands.The band loop can be attached to the case using one or more rivets orother fastening means to the back flap.

FIG. 8 shows positioning of hinge 129 behind the sleeve. For example,this position may be about 80 millimeters from the edge 940, where anoverall length of the back flap is 200 millimeters. Therefore, hinge 129is closer to edge 940 than hinge 234 (or the spine). The hinge may bepositioned at about 40 percent of the length of the back flap. So about40 percent of the flap is attached to the sleeve, while about 60 percentis unattached.

In various implementations, the positioning of the hinge behind thesleeve can vary. For example, the hinge may be positioned from about 25to about 75 percent the length of the back flap (e.g., 30, 33, 45, 60,or other percent).

In a further implementation of the case, hinge 129 is positioned at edge940, so the entire back flap is not attached to the sleeve except at thehinge. With this positioning of hinge 129, viewing angles 1, 2, and 3described above will be available, but the working angle will beomitted.

In a specific implementation, the cover includes a left, top, right, andbottom cover edges which may be referred to as first, second, third, andfourth cover edges. A front flap of the cover is from the first coveredge to hinge 238. The front flap has a first length from the firstcover edge to hinge 238 that is sufficiently long to cover a frontscreen of the electronic device when the front flap is folded via thefirst hinge to close the case. A second length is from the third coveredge to hinge 129. A third length is from hinge 129 to hinge 238. In aspecific implementation, the third length is greater than the secondlength. In another specific implementation, the third and second lengthare equal. In another specific implementation, the second length isgreater than the third length.

In a specific implementation, a sum of the first, second, and thirdlengths is at least about 407 millimeters. A length of hinge 238 is atleast about 245 millimeters. These dimensions can vary depending uponthe case materials, the portable electronic device the case is designedto hold, or both.

Some specific techniques for attaching materials have been described inthis application. However, any attachment technique or mechanism may beused to attach or bond the case pieces together. Attachment may be byway of an adhesive such as a glue (e.g., fabric glue) or epoxy. To helpfacilitate bonding, a bonding agent can be used. For example, portionsor the entire surface of the fixed back flap can include a temperatureactivated adhesive that helps bond the sleeve and back flap togetherwhen heat, pressure, or both is applied. Such an adhesive can be in theform of a coating, powder, or lacquer, such as a heat sealing lacquer.Sufficient heat is applied in order to bring the temperature up to orabove the activation temperature of the adhesive. Curing can occur uponcooling. Using such a bonding or adhesive process to make the caseallows the case to be made quickly and cost effectively and very littlelabor is used.

Attachment may be by way of stitches or stitching. In this specificimplementation, in a first attachment step, the sleeve is positionedover the back flap. In a second attachment step, the sleeve is stitchedto the fixed back flap, but is not stitched to the movable back flap.The stitching process may include using a needle and thread. Thestitching may be done using a sewing machine or may be done by hand.

Attachment may be by way of rivets. A rivet is a pin or bolt of material(e.g., metal) used for uniting two or more pieces. One end of the rivetshank has a head and an opposite end of the shank has a plain end. Theplain end passes through a hole in each piece. The diameter of the headis larger than the diameter of the hole so that the rivet can not passcompletely through. After passing the plain end through the hole, theplain end is beat or pressed down so as to make an another head having adiameter larger than the diameter of the hole—thus securing the materialpieces together between the heads.

Attachment may be by way of welding such as plastic welding or radiofrequency (RF) bonding to seal or bond the sleeve to the fixed backpanel portion, but not the movable back panel portion. Some examples ofspecific welding techniques that may be used include hot gas welding,freehand welding, speed tip welding, extrusion welding, contact welding,hot plate welding, high frequency welding, injection welding, ultrasonicwelding, friction welding, spin welding, laser welding, or solventwelding.

These techniques are intended to create a permanent bond between thesleeve and the fixed back flap. However, in another implementation, theattachment mechanism permits the user to separate the sleeve from theback flap or outer cover. For example, the user may remove a sleeve froma first outer cover. The user may then attach the sleeve to a secondouter cover, different from the first outer cover. For example, a colorof or image on the first outer cover may be different from a color of orimage on the second outer cover. Such a feature can be used to permitthe user to coordinate or match the color of their clothes with thecolor of the case. The feature can also allow the user to replace justthe outer cover (and keep the sleeve) when the outer cover becomesdamaged or worn.

In this specific implementation, an attachment includes a hook-and-loopattachment mechanism (e.g., Velcro). Other nonpermanent attachmentmechanisms that allow the user to replace the outer cover includezippers, latches, buckles, buttons, straps, tongue and groove, and thelike.

Theelectronic device is inserted into frame 1302 through the front opening.Unlike the sleeve of FIG. 2A which has a slot 247 (FIG. 2H), frame 1302has four sides without a slot into which to slide the electronic device.The sides of the frame have openings and over-molded buttons to allowaccess to the ports and buttons of device.

The frame is made from an elastic material which allows the frame to bestretched around the sides of the electronic device. The electronicdevice may be fitted into the frame through the front opening of thebezel by peeling back the bezel so as to enlarge the front opening. Theelectronic device can be fitted into the enlarged front opening. Uponreleasing the bezel, the bezel can recover its former size so as to holdthe electronic device. In this specific implementation, the bezel ismade of an elastic material (e.g., rubber, latex, or silicone) to permitthe bezel to be stretched.

Compared to grooves 206, 208, and 210 in the FIG. 2A embodiment, thisembodiment uses over-molded rails 1305 as edge stops. The rails are overmolded on the base surface or the inside surface of the front flap. In aspecific implementation, there are three rails, but as was the case forthe grooves, there can be more rails (to support a greater number ofviewing angles), fewer rails, or a combination of rails and grooves.

Each rail is formed as a line that extends across at least a portion ofthe base surface as shown in FIG. 13. Although possible, each rail doesnot necessarily extend entirely across the base surface. A single railcan stop the edge of the frame from sliding in one direction (e.g.,forwards) along the base surface when the frame edge butts up againstthe rail. In comparison, a single groove can prevent the sleeve fromslipping in two directions (e.g., forwards and backwards).

FIG. 14 shows a back perspective view of the case in one of the viewingangles. The frame has a full thermoplastic polyurethane (TPU) back 1410.The frame is attached to the back flap by adhesion. For example, theframe can be attached to the outer cover by using an adhesive, bonding,fusing, or other adhesion technique. An adhesion area 1405 (OP tothermoplastic elastomer (TPE)) indicates the attachment of the frame tothe back flap.

When the case is folded into a stand as shown in FIG. 14, a back of theelectronic device is still protected because the back remains covered orcompletely covered by the backing of the frame.

This case hasa thickness of about 30.5 millimeters (about 1.2 inches).

It should be appreciated that the case sleeve (FIG. 2A) and case frame(FIGS. 13 and 35) are merely examples of how the electronic device maybe retained against the cover. Any retaining mechanism may be used toremovably hold the electronic device against the cover so long as aportion of the back flap can be folded away from the electronic deviceso that the cover can be folded into a stand. In a specificimplementation, a set of clips attached to the cover is used toremovably hold the electronic device against the cover. In this specificimplementation, a first clip is attached to the second cover edge, and asecond clip is attached to the fourth cover edge. The first clip ispositioned along the second cover edge so that it is between the firsthinge and the third cover edge. The second clip is similarly positionedon the fourth cover edge. That is, the second clip is positioned alongthe fourth cover edge so that it is between the first hinge and thethird cover edge. The first hinge will be behind the electronic devicewhen the electronic device is in the case.

This position of the first and second clips allows the back flap (or theportion of the back flap not connected to the electronic device) to befolded away from the electronic device via the first hinge when foldingthe case into a stand.

In a specific implementation, the clips are rigid. To insert theelectronic device into the case, the electronic device is slidunderneath the clips in a direction from the first hinge towards thethird cover edge. In this specific implementation, the cover includesone or more guards or stops to prevent the electronic device fromsliding past the third cover edge. In a specific implementation, thereare two guards. A first guard is attached to a first corner of the coverdefined by the intersection of the second and third cover edges. Asecond guard is attached to a second corner of the cover defined by thefourth and third cover edges. A guard may be placed anywhere along thethird cover edge to stop the electronic device from sliding past thethird cover edge. A guard may be referred to as a bumper, corner guard,wall, or tab.

In another specific implementation, the clips are bendable or flexible.To insert the electronic device the clips are bent around an edge of theelectronic device. Upon release of the clip, the clip recovers itsprevious form. A clip may be referred to as bracket, grip, claw,pincher, or hook.

In a specific implementation, a case cover includes a set of grooves anda clasp. The clasp is attached to the first cover edge. The clasp canact as a stop for the electronic device and provide one of the viewingor working angles. The clasp can also act as a closure mechanism to holdthe front and back flaps of the case together when the case is closed.For example, the clasp can be removably fastened to the third coveredge. In this specific implementation, the clasp is designed to snap inand out of place and is made of a flexible material. In another specificimplementation, a strap having a button, Velcro, or both is used tofasten the front and back flaps of the case together when the case isclosed.

In a specific implementation, there are four grooves and a clasp. Theclasp and grooves allow the electronic device to be positioned at one offive different angles. The clasp provides the angle having the mostslope. Although in this specific implementation there are four grooves,as discussed above, there can be any number of grooves.
